Good evening! Really enjoyed the course, it was very informative! :) I wanted to find out two things: 1. What is the best way to clean the buckets etc afterwards if its not disposable items like the coloured cups? 2. Where can I get the pigments you mentioned? I am in South Africa and can only seem to find Mica powders which mostly have that very metallic look. Other more solid colours there is only a very primary blue available in most places. Thanks so much Lauren!
